In a new study published by the Sekijima Laboratory, researchers were able to achieve a 10x acceleration and 75% energy reduction on TSUBAME2.0 running a molecular dynamics simulation of a biomolecule:

In this study, we performed molecular dynamics simulation using GPU on TSUBAME2.0 supercomputer. Then the performance performance and result was compared to those of conventional CPU molecular dynamics regarding calculation speed, energy consumption and accuracy. Our experiment showed that using GPUs could yield a great improvement in both the calculation speed and energy consumption. Comparing 8 nodes 16 GPUs result and 8 nodes 96 CPU cores result, we could achieve about 10 times acceleration and 75 % energy reduction. And the results of GPU molecular dynamics was consistent with that of CPU molecular dynamics within acceptable range.

In this episode, the Radio Free HPC team splits on the topic of Net Neutrality. The FCC will soon publish its new rules for ensuring an even playing field for Internet Bandwidth. "Dan doesn't like the idea one bit. Henry disagrees and thinks we need Net Neutrality to keep the Comcasts of the world from running amok. As for Rich, he just finds the whole argument rather amusing since it's pretty much a done deal." [Read More...]
